Most cases of accessory spleen show similar features as normal spleen in imaging studies. However, some accessory spleen has unusual scan feature which can be misdiagnosed. We present a case of intrapancreatic accessory spleen that was discovered incidentally during a workup for abdominal pain in a 47-year-old woman. CT and MRI revealed a different enhancing pattern from that of the spleen. Further evaluation with endoscopic ultrasonography failed to identify the pancreatic mass. Therefore, it was surgically removed and diagnosed pathologically as an accessory spleen.

PURPOSE: To investigate the clinical manifestations and treatments of parafoveal telangiectasis. METHODS: Twenty-two eyes of fifteen patients diagnosed as parafoveal telangiectasis were selected who had visited Kong Eye Center from September 1999 to August 2003 complaining of decreasing visual acuity. Visual acuity was checked and fluorescein angiography and optical coherence tomography were done. Authors treated six eyes of six patients experienced decreasing visual acuity due to macular edema with argon laser photocoagulation and one eye of one patient accompanying with choroidal neovascularization with photodynamic therapy. RESULTS: Among fifteen patients, group 1 cases were eight (1B eight) and group 2 cases were seven by classification of Gass and Blodi. Visual acuity improved in two eyes of six eyes and maintained in four eyes of six eyes and optical coherence tomography showed decrease of macular edema in six eyes of six patients all after argon laser photocoagulation. Visual acuity improved and optical coherence tomography showed decrease of macular edema in one eye of one patient after photodynamic therapy. CONCLUSIONS: Group 1 cases were more than group 2 cases. Argon laser photocoagulation can be effectively used to treat decreasing visual acuity due to macular edema in parafoveal telangiectasis patients. Photodynamic therapy seems to be effective in parafoveal telangiectasis accompanied with choroidal neovascularization but we think that additional studies with more cases are needed.

PURPOSE: To report two cases of spontaneous resolution of macular hole stage 1 and 2, that were objectively diagnosed with OCT(optical coherence tomography). METHODS: Case 1-A 64-year-old woman without systemic disease visited Kong Eye Center complaining of decreasing visual acuity for 1 month. We diagnosed her case as macular hole stage 1, checked her regularly and detected spontaneous resolution of the macular hole after 6 months. We examined her using OCT before and after spontaneous resolution. Case 2-A 66-year-old man without systemic disease visited Kong Eye Center complaining of decreasing visual acuity for several months. We diagnosed his case as macular hole stage 2 and decided to perform an operation 3 weeks later. On admission, we detected spontaneous resolution of the macular hole. We examined him using OCT before and after spontaneous resolution. RESULTS: We could confirm the spontaneous resolution of stage 1 and 2 macular hole using OCT objectively. CONCLUSIONS: OCT is a useful tool in the diagnosis of macular hole and in the evaluation of various natural course of macular hole.

PURPOSE: To determine the benefit of optical coherence tomography (OCT) in the diagnosis of vitreomacular traction syndrome and evaluate the vitreoretinal interface before and after vitreous surgery. METHODS: Medical records of five patients with vitreomacular traction syndrome who had undergone vitrectomy were reviewed. Preoperative and postoperative visual acuity and preoperative and postoperative OCT were reviewed. In all patients OCT demonstrated posterior vitreous detachment and a focal adhesion of hyaloid membrane to macula with traction on the foveal retinal tissue. All of them underwent pars plana vitrectomy with peeling of poterior hyaloid face. RESULTS: Visual acuity improved in 4 eyes after the first vitrectomy. One eye developed postoperatively a macular hole, which was treated with the second vitrectomy and intravitreal gas tamponade with subsequent improvement in vision. In 4 eyes, OCT showed elimination of vitreous strand, relief of vitreous traction and restoration of normal foveal contour after vitrectomy. CONCLUSION: Optical coherence tomography is a useful tool in the diagnosis of vitreomacular traction syndrome and in the evaluation of status of vitreoretinal interface before and after vitrectomy. Following pars plana vitrectomy, vision improved and normal foveal contour was restored.

BACKGROUND AND OBJECTIVES: High-resolution computed tomography provides an excellent method for examination of the middle ear, inner ear anatomy and pathologic changes in the temporal bones. The purpose of this study was to get various measurements of the external auditory canal and temporal bones, and to compare the changes with age and sex. MATERIALS AND METHOD: The various measurements by CT of the external ear canal of normal 50 ears were done. RESULTS: The obtained results were as follows: 1) In both male and female group, the distance from the medial end of EAC to bony-cartilage junction, the distance from medial end of EAC to the lateral end of cartilage, the distance from the superior wall to the inferior wall (coronal EAC isthmus) and the distance from anterior wall to the posterior wall (axial EAC isthmus) increased significantly with age (p<0.05). 2) Compared with the female group, the male group had longer distance from the posterior tympanic plate to the sinus tympani with age (p<0.05). 3) Compared with male group, the female group had longer distance from the posterior EAC wall to the Sigmoid sinus and from the EAC superior wall to the tegmen tympani with age (p<0.05). 4) In both male and female groups, the anterior and inferior angles increased and the posterior and superior angles decreased with age (p<0.05). CONCLUSION: Computed tomographic evaluation can give us to information to operate external ear, middle ear, and inner ear surgery.

Congenital absence of the major salivary glands, especially of the parotid gland, is a rare disorder whose etiopathogenesis is poorly understood. Aplasia of the parotid glands may be unilateral or bilateral and may occur alone or in association with the absence of other salivary glands or with other developmental anomalies of the first branchial arch, such as hypoplasia or aplasia of the lacrimal glands, hemifacial microsomia, mandibulofacial dysostoses, and multiple congenital anomalies. Various degree of xerostomia and dental caries with early loss of teeth may occur due to decreased salivary production. The authors experienced a case of unilateral parotid aplasia in a 22-year old female who had painless swelling in the right parotid region. We present this case with review of literature.

BACKGROUND AND OBJECTIVES: Some patients who have undergone tonsillectomy complain of voice change, but few studies for the mechanism of voice change were found. To solve this problem, study of voice change after tonsillectomy and adenotonsillectomy was done. MATERIALS AND METHODS: We analyzed voice change of 22 patients who underwent tonsillectomy and 15 patients who underwent adenotonsillectomy at CSL (computerized speech laboratory), St. Benedict Hospital. With the measured cross sectional area of vocal tract and its length from the glottis on MR images, we presented the change of cross sectional area schematically after tonsillectomy. RESULTS: Acoustically, the frequencies of the second formant of /e/ and /i/ increased and that of the first formant of /u/ decreased significantly after tonsillectomy and the frequency of the second formant of /o/ and those of the second and third formants of /i/ and /u/ increased significantly after adenotonsillectomy. It was also showed acoustically that the formant bandwidths of /a/ and /hana/ after tonsillectomy and those of /e/ and /hana/ after adenotonsillectomy increased due to nasalization. Anatomically, it was showed that the cross sectional area of oropharyngeal cavity increased and coupling effect of vocal tract happened after tonsillectomy. CONCLUSION: This study showed that acoustic characteristics and vocal tract shapes of the patients did change following tonsillectomy and adenotonsillectomy. It is imperative that we explain to patients about the postoperative voice change. Research should also be done to find ways to induce better voice changes following the operations.

BACKGROUND AND OBJECTIVES: The kinds of offending allergens in our environment have changed in accordance with the changes wrought in the living environment. Thus, the study of offending allergens in allergic rhinitis is important. This study attempted to find out annual and seasonal distribution of offending allergens in patients of allergic rhinitis and to investigate the common offending allergens. MATERIALS AND METHODS: A series of allergic skin tests were performed for 3,159 allergic rhinitis patients from Jan. 1981 to Jun. 1990 at the allergic clinic, St.Benedict Hospital, Pusan, Korea, and the results were reviewed. The allergic study included 1) an allergic skin test, 2) a nasal smear for eosinophil. RESULTS: The following summary shows the results of this study: 1) The ratio between male and female of allergic rhinitis patients was 1.15:1 with the peak age being the teens and the twenties (60.6%). 2) The peak season of allergic rhinitis was winter (29.6%), followed by autumn, spring and summer. 3) The common offending allergens were dust and mites (35.9%), pollens (31.2%), epithelials (24.8%). 4) The most common offending allergen was D. farinae (52.5%), followed by D. pteronyssinus, cat fur, Alder pollens and Hazel pollens. 5) 29.6% of patients reacted positive to the skin tests for perennial types of allergens only and 5.2% of patients demonstrated pure pollinosis. CONCLUSION: The most common offending allergen was found to be the dust mite, and the most common pollen was from Alder trees. Perennial types of allergic rhinitis exceeded seasonal types in their occurence.

BACKGROUND AND OBJECTIVES: Using sophisticated imaging techniques, such as x-ray cephalometry, computed tomography, and magnetic resonance imaging, we found obstructive sleep apnea patients to have smaller upper airways than nonapneic individuals. The purpose of this study was to examine whether a simple test, such as routine roentgenographic views of the upper airway, is useful in identifying anatomic narrowing of the airway in patients with sleep apnea. MATERIALS AND METHODS: We carried out a prospective study of a group of 30 patients (28 male and 2 female subjects) referred for evaluation of heavy snoring and possible obstructive sleep apnea. All patients had full nocturnal polysomnography and the lateral views of their airways were used to measure the pharyngeal diameters at three sites along the airway. All measurements were performed with the patients positioned both upright and supine. RESULTS: We observed that obstructive sleep apnea patients maintained significantly lower the retropalatal distance in the supine position than in the upright position. CONCLUSION: We concluded that routine roentgenographic measurements of upper airway diameters are useful screening methods for patients suspected of having sleep apnea.

BACKGROUND AND OBJECTIVES: A history of poor weight gain can often be elicited in young children with chronic upper airway obstruction resulting from adenotonsillar hypertrophy. The purpose of this study was to determine the incidence of growth disturbance and what effect, if any tonsillectomy and/or adenoidectomy has on subsequent growth in a group of children. MATERIALS AND METHODS: The subjects consisted of 78 patients with adenotonsillar hypertrophy who had been treated between March 1997 and September 1997 at the department of otolaryngology, Saint Benedict Hospital. Available preoperative data were collected including sex, age at surgery, tonsillar hypertrophy grade, presence of snoring and sleep apnea, preoperative weight, preoperative eating disorder, and URI frequency. RESULT: Many had improvements in growth after adenotonsil-lectomy. The improvement in growth appears to be obvious in chidren with eating disorder, snoring, and sleep apnea resulting from adenotonsillar hypertrophy. CONCLUSION: We can conclude that there exists a relationship beween adenotonsillar hypertrophy children and preoperative eating disorder, growth delay and snoring.
